FRUIT-DRIER.

SPECIFICATION forming part of Letters Patent No. 255,602, dated March 28, 1882,

\ Application filed January 21, 1882. (No model.)

and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure l is a longitudinal vertical section.

Fig. 2 is a horizontal section on the line a; as, Fig. 1; Fig. 3, a horizontal section on the line 3 3 Fig. 1; and Fig. 4 is a perspective view of the slide and tray.

My invention relates to means for drying fruit and vegetables; and my object is mainly to furnish an apparatus which will efi'eet the drying of the substances rapidly and uniformly, and w ich is so constructed that hot or cold air can be used, and the same distributed over a very large surface and regulated in a convenient manner.

In carrying out my invention I employ a fur nace at the base of the apparatus, which is provided on two sides with doors, and on two sides with air-channels and air-inlet passages having regulating caps or dampers. I also employ inside of the body of the driera smokepipe communicating with the furnace, and also with the external air through the roof. I also employ removable frames having hinged sections and doors, and adapted to support the trays on which the substances to be dried are supported, and I construct the trays with supporting-spiders,wl1ioh are provided with means for tightening them.

The following is a description of my improvements.

A designates the body of the dryinghouse constructed of two side walls and transverse connecting-bars suitably mounted on the walls which inolose the furnace B and the air circulating channels 0 G on opposite sides thereof.- The side walls of the body A are provided with narrow horizontal rests a, forming supports for removable frames D, on which the fruit-trays E are placed.

The furnace-chamber B is provided with doors I) at its ends, a covering-plate, F, and a second cover, F, through which are holes for have openings through them for the admission of air, which openings are provided with suitable dampers, d, for regulating the admission of the air. There is also a short horizontal pipe, 0, which passes through one of the channels 0 provided with a damper, f, for regulating the admission of air to the furnace-chamber B.

G designates a pipe rising from the top of the furnace-chamber B, and communicating with a horizontal coiled heating drum, G, arranged in the body A of the drier and suitahly sustained therein, and from this drum Gr rises an outlet'pipe for the products of combustion, which passes out through the center of pitched roof A. The heat from the outflowing products of combustion is radiated in all directions from the drum and its pipes and uniformlydistributed throughoutthedrying-apartment. I provide openings through the side and walls of the roof A for the escape of the vitiated and damp air, which openings have doors 9 applied to them for regulating the out;

let of the air, and for closing them on that side ot' the apparatus against which the wind blows.

The frames D, which are supported on the rests a, are rectangular and have short hinged sections h, and also narrow doors 1', applied to their front ends. When the frames are in their" places the top and bottom edges abut so as to tightly close the ends of the body A. The hinged sections it of the frames D will drop down when these frames are partly withdrawn from the drying apartment, and allow the fruit on the trays E to be inspected. It is obvious that very little cold air will enterthe apartment A when a frame, D, is partly withdrawn from it, owing to the doors ibeing made very narrow.

Each tray E is a rectangular frame adapted to rest upon a frame, 1), and provided with a spider consisting of a central ring, j, a crossbar for supporting the same, diagonal wires it, connected to it and also to angular cornerpieees l, which are provided with nuts on their ends by which the entire spider can be tightened when necessary. This spider is designed to support the Wire-cloth on which the fruit is pieces, and the tightening-nuts, substantially put to dry. as described.

Having thus fully described my invention, In testimony that claim the foregoing as what I claim as neW,and desire to secure by my own I affix my signature in presence of 5 Letters Patent, is-- two witnesses.

1. The combination of the sectional hinged frame D and the door applied to this frame, for the purpose specified. \Vitnesses:

2. The combination of the tray-frame, the 'l. P. HACKLEMAN, 1o spider stretched therein, the angular corner- D. R. N. BLACKBURN.
